Casey, who turned 20 on Wednesday, is Jamie Lynn Spears' boyfriend and the father of their 10-month old daughter, Maddie. The star reportedly stood by her man this week, spending time at the hospital and riding with him in the ambulance on the way to the Medical Center.

Odus Jackson, Casey's uncle, told Access Hollywood on Tuesday that the young man had already been moved out of the intensive care unit and was up and about.

"The room therapist has been walking him," Odus said at the time. "He should be out of the hospital in a couple of days if everything stays as it is. All the scans look good."
